Abstract: Features described herein pertain to smart thermostats, and more particularly, display control mechanisms for smart thermostats. A smart thermostat can include a display, an ambient light sensor, and a radar sensor. Using the ambient light sensor, an ambient light level of an environment surrounding the smart thermostat can be measured. Radar data can be received from the radar sensor, and based on the radar data, a determination can be made that a distance between a person and the smart thermostat has changed from a first distance to a second distance. In response, a display brightness of the display can be adjusted based on the ambient light level.

Abstract: Heat exchangers include a housing with an internal structure that defines sets of first and second fluid passages such that a first fluid within the first fluid passages is prevented from mixing with a second fluid in the second fluid passages. An inlet manifold defines an inlet plenum for receiving the first fluid and directing the first fluid into openings of the first fluid passages. The openings are defined in an inlet end face of the internal structure within the inlet manifold. A set of flow directors are arranged on the inlet end face and are configured to direct a flow of the first fluid into the openings of the set of first fluid passages, with each flow director defining an end face passage that is one of the second fluid passages of the set of second fluid passages.
